Set up for a bar gig last night. when I powered up my DXR10s and Kemper there was a high pitch ringing,the volume was not really loud but present. powered down the kemper and the pitch got lower and a little louder. I had this happen one other time. I did lift the ground to the monitors and it got better. Wondering if a good rf filter would have helped this. Didn't see any neon signs in the bar. Anyone else have similar issues and found a good solution? Otherwise the kemper sounded awesome! Thanks.

Sounds like the issue was external to the Kemper, otherwise the ground-lift tweak wouldn't have alleviated the problem, albeit to only a minor extent.
Sorry mate; I've got nothin'.

Thanks for the reply. When I unplugged the Kemper from the monitors they were dead quiet. when I plugged them back in it came back or got a little worse. Everything was plugged into the same power strip. Just curious if anyone else has had this problem.

I've used my DXR10 at 150 or so gigs, and have never had a high pitch ringing sound problem.

I have the same problem. What helped me, was to put a line isolator in between the monitor out of the Kemper and the line in of the DXR (input 2). I use a Radial Engineering Sb6. It seems it has something to do with ground loops.

Thanks Ronald V. I will look into this.

When it happens again I guess I will record it and open a support ticket. Seems as only one other person has had this problem it must be a problem with the unit.
